Strange P3A gps condition.

Hi Today when I was flying the P3A at 88 meters directly above me I got a notification "safe to fly(no gps)" while I had locked to 13 sats. Warning flashed 2-3 times for a couple of seconds and then the rest of the flight went without incident. During the whole time I had full rc signal and video signal and from 10 to 14 satellites locked.
K index was 3 today.
Any ideas will be greatlly appreciated.

We are saying the same thing. RC and HD signal 5 bars. The times I have noticed this are when I am coming back home, up high. 200ft or so.
Sometimes I don't notice until after as when it is that close I am looking directly at the P3 for landing. Not at the screen.
It has never made any difference to the control of the AC.
